Copy of response to original email query:

Hi Kyle, Tom, Jaydip,
I would refer you to the art stakeholders meeting slides describing the resolution to the problem described in issue 23013. Unfortunately, based on the error message you relate below, you are not having trouble specifically with the double -> Double32_t aspect of the schema evolution here. The data product you're having trouble with had two relevant changes: a nested object changed from vector<ROOT::Math::PositionVector3D<ROOT::Math::Cartesian3D<double>,ROOT::Math::DefaultCoordinateSystemTag> > to vector<ROOT::Math::PositionVector3D<ROOT::Math::Cartesian3D<double>,ROOT::Math::GlobalCoordinateSystemTag> >, and then subsequently to vector<ROOT::Math::PositionVector3D<ROOT::Math::Cartesian3D<Double32_t>,ROOT::Math::GlobalCoordinateSystemTag> > (changes in red / bold). The latter change is the one that has been resolved in the current LArSoft by updating to a recent ROOT and removing the related I/O rule entirely; unfortunately your data file is sufficiently old that the former change must also be accounted for, and that is an aspect of the ROOT issue https://sft.its.cern.ch/jira/projects/ROOT/issues/ROOT-10271 that has not been addressed to date.

I have CC'd the ROOT developer currently working on the problem. Please enter a Redmine issue with the full specifics of the problem, and I will add a reference to it in the upstream ROOT issue.

We are sorry that you are experiencing this, but the TL;DR is that you will be unable to read these older files with ROOT >= 6.16/00 until the underlying ROOT issue is fixed. While understood as urgent by the ROOT developers, there is not currently a timeline for resolving this.

Best,

Chris.

We will escalate this with the ROOT team. Philippe was notified upon receipt of the original email last week, and now there is a ticket in the Redmine system it will be added to the JIRA ticket.
